I’m debating between a neo or traditional Le Pliage 1899 bag. I usually use the 1899, but wondered if the strap and the ability to use it as a crossbody would be better when walking around and sightseeing. I’d love to use my Le Pliage backback, but I’ve heard backpacks are a bad idea generally in Europe. What have you gals used on your trips? Pros and cons of each bag? Thanks in advance for your input.
